Potential of Fly Ash Utilization for the Clinker Substitution in Cement Industry in Thailand

The main objective of this article is to forecast CO2 mitigation from clinker production and to evaluate Fly Ash potential, used Clinker Substitution for CO2 mitigation in cement industry between years 2015-2036 in Thailand following information of the Thailand's power developments plan (PDP2015). PDP2015 forecasts the potential of fly ash in the year 2036 which is estimated at 3.94 M ton and 48.76 M TonCO2 of CO2 emission from 58.01 M Ton of clinker production process. The methodology which is used for potential evaluation of fly ash and amount of CO2 can evaluate from Mae Moh power plant technology. 1 MW can occur 952.3427 Ton and amount of CO2 emission from utilizing is 0.825 TonCO2/TonneCli which is a default value of CSI (Cement Sustainability Initiative).The three different scenarios are used to analysis in this study. The condition of Business As Usual (BAU) scenario is the need of technology, used in 2015 as a base case. The full potential scenario (FP) is represent to the 100% fly ash using. The final scenario is called Zoning scenario (Z scenario) which consists of price rate (270 THB per Ton) and transportation rate (6 THB per kilometer of fly ash). From the result, in 2036 fly ash occur 7.46 M Ton that can mitigate CO2 volume up to 6.15 M TonCO2

Approximately 7 million tons of fly ash and slag are produced in thermal power plants in Serbia every year, only 3% of which is used in the cement industry. About 300 million tons of the ash-slag mixture are disposed in landfills, occupying an area of approximately 1600 hectares and generating environmental issues. Fly ash from Serbian power plants has pozzolanic properties and due to low concentration of calcium compounds (less than 10% CaO), they do not have self-cementing properties. According to the ASTM C618-15, this ash is from class F. According to the European Standard EN 197-1:2011, this ash is siliceous (type V) ash. From April 2014 to May 2015, an investigation of engineering properties of fly ash and mixtures of fly ash and slag from landfill (without or with binders of cement/lime) was conducted at the Laboratory of Soil Mechanics at the Faculty of Civil Engineering of the University of Belgrade (Serbia) and at the Institute for Testing of Materials – IMS Institute in Belgrade. The laboratory test results were showed in the study ‘Utilization of fly ash and slag produced in the TPP JP EPS thermal power plants for construction of railways’. Four kinds of waste materials from Serbian power plants were laboratory tested: (a) an ash-slag mixture from landfills at the ‘Nikola Tesla A’ thermal power plant; (b) fly ash from silos in the ‘Nikola Tesla B’ thermal power plant; (c) an ash-slag mixture from landfills at the ‘Kostolac A’ and ‘Kostolac B’ thermal power plants and ‘Srednje kostolačko ostrvo’ landfill; (d) fly ash from the ‘Kostolac’ thermal power plant. The following physical and mechanical properties of ash and mixtures were investigated: grain size distribution, Atterberg limits, specific gravity, moisture-density relationship, shear strength parameters in terms of effective stresses, California Bearing Ratio (CBR), and deformation parameters. The paper presents the results of laboratory tests of the materials with and without binders, and based on the laboratory results and previous research, the paper presents possibilities of using fly ash and slag for the construction of railway substructure in the planned construction and reconstruction of railway network in Serbia. The obtained results indicate that tested fly ash and ash-slag mixture have met the technical requirements and that they have the potential to be used in railway substructure.

The cenosphere is one becoming a focus of the power plant in terms of value addition and ash management. This study presents a systematic investigation and characterization of physical properties, morphological structures, and chemical composition of cenospheres separated from fly ash produced from the Mae Moh coal-fired power plant, Thailand. To our knowledge, this is the first report on cenospheres separation from Mae Moh class C fly ash, with high calcium content ~24 wt.%, by adopting the traditional wet separation method (using water as the medium) to separate the lightweight cenospheres. Various effects of process parameters (fly ash-to-water ratio, stirring method, ultrasonication, and size classification) were designed to examine the cenosphere recovery yield in comparison. The result has revealed the limit of physical stirring-settling effect associated with the cenospheres content by nature governing the percent recovery. The bulk cenospheres were subject to size sieving into different sized fractions, with the structure-chemical composition relationship established for more insight. The particle diameter/shell thickness ratio revealed its significant correlation with the aluminosilicate glass composition, with the relating cenosphere shell structures (single-ring and porous) mapped to compare for a better elucidation of their structure-property relationship. The phase composition was also studied.

This research study about the abatement cost of CO2 reduction by using fly ash as a clinker substitute in Thailand cement industry. And also present the sensitivity analysis about the factors that affect the abatement cost. The proportion of quantity to use fly ash as a clinker is equal to 1: 1 ton, therefor will calculate at 1 ton of clinker which make the quantity of mitigated CO2 in this research is equal to 0.825 tonCO2/year. Use the information in year 2015 to analyze, such as the exchange rate, fly ash price and transportation rate. And use average distance of fly ash transportation from the power plant to cement plant to calculate. From the information, the approach to reduce CO2 by this method is without additional investment. Because fly ash is small it can be mixed with clinker before grinding step of the original process. The CO2 abatement cost of this method is equal to -106.16 USD/tonCO2, which is regarded as a worthwhile investment. The factor is the most affect to mitigation cost is transportation rates. The transportation current rate is 0.092 USD/ton/km but if it increases, the abatement cost will also increase accordingly. Moreover we also calculate the maximum distance to decide on the purchase of fly ash from each of power plant.

The influence of fly ash adittion (90 % fraction [ 100 mm) on the cement mortar characteristics was studied. The XRD, XRF, SEM and FTIR determinations indicated that fly ash used has a hollow microstructure of microsphere and cenosphere whose total content in SiO2, Al2O3 and Fe2O3 is 88.63 % and that of CaO and MgO of 8.55 %. The mechanical, thermal and dielectric determinations made on mortar samples with content of fly ash in the 0-40 % range have highlighted fact that the mechanical strength of cement mortars is maximal at 20 %, the increase in fly ash content leads to a decrease in relative density and thermal conductivity as well as and to increased dielectric losses tgd.

High Performance Composite

Given the amount of industrial waste produced and collected in the world today, a recycling and recovery process is needed. The study carried out on this subject focuses on the valorization of one of these industrial wastes, namely the fly ash produced by an ultra-supercritical coal power plant. This paper describes the use and recovery of fly ash as a high percentage reinforcement for the development of a new high-performance composite material for use in various fields. The raw material, fly ash, comes from the staged combustion of coal, which occurs in the furnace of an ultra-supercritical boiler of a coal-fired power plant. Mechanical compression, thermal conductivity, and erosion tests are used to study the mechanical, thermal, and erosion behavior of this new composite material. The mineralogical and textural analyses of samples were characterized using Scanning Electron Microscopy (SEM). SEM confirmed the formation of a new composite by a polymerization reaction. The results obtained are very remarkable, with a high Young’s modulus and a criterion of insulation, which approves the presence of a potential to be exploited in the different fields of materials. In conclusion, the composite material presented in this study has great potential for building material and could represent interesting candidates for the smart city.
